' Like characters of reference indicate corresponding parts throughout the several Views.

As in the aforesaid co-pending applications'the present invention comprises a base or frame 25 in the form of a housing and flooring which contains and incloses the entire mechanism.

Upon the floor of the frame or housing 25 are tracks 26 provided with any approved friction reducing means as the balls 27 upon which is mounted to reciprocate a carriage 28. The carriage 28 is reciprocatedin any approved manner as by means of sprocket chains -29 passing over sprockets 30 and.31 and driven by other sprocket chains 32 receiving motion from the drive shaft 33 which in turn receives motion through the agency of the worm 34 and gear 35 from another sprocket chain 36 receiving. motion from the main sprocket 37 from the motor 38.' Motion from the sprocket 37 is also transmitted to the squared or multi-angular shafts 39 which extend longitudinally throughout the greater portion of the length of the machine.

he carriage 28 carries a sprocket 40 mounted to slide longitudinally upon one of the shafts 39 and over such sprocket passes a sprocket chain 41 which in turn passes over a sprocket 42 upon the shaft 43 which is journaled in a bearing 44 and carries a bevel pinion 45 for driving the several Mounted also upon the bearing 44 accommodating a sprocket chain 48.

'The frame 46 provides bearings as at 49 for the brushes pivotally connected with the frame by means of drive shafts 51 to permit the movement of such brushes in a plane parallel with thedriving shaft 43 and held in operative position by means of springs 52, with adjusting bolts 52 for limiting the return movement.

The frame 46 also provides bearings for the auxiliary frames 53 which carry brushes 53 and the latter receive motion by means of sprocket chains 54 and 55 from the drive shafts 51. The main frame, auxiliary and driving such brushes is substantially similar to the same features disclosed insaid co-pending application 428,187, and need no further description here.

To rotate the frame 46 and therewith the push switch closed. 'Fig. 18 is a view of the push switch open. Fig. 19

50, such bearings 49 being.

brushes carried thereby tochange the brushes operating upon the foot, the chain 48, which connects with the sprocket 47 of such frame, passes also over a sprocket 56 carried upon a shaft 57 which carries spiral or helical fins 58. The shaft 57 is journaled in brackets 59 and. 60 mounted upon the carriage 28 and reciprocating therewith.

Adjacent the path of movement of the carriage a pillar 61 is erected having a U- shaped top portion 62 carrying two rollers 63 disposed upon opposite sides of the shaft 57 and in position to ride along the tops of the helical fins 58. The result of such action is that as the shaft 57 reciprocates beneath such rollers 63 it is alternately rotated through half a circumference and return.. The shaft 57 carries a detent 64 positimed to engage sockets 65 inthe hub of the sprocket 56 to lock the shaft 57 and the a hub to rotate together. The pillar 61 carries a block 66 in such position that in passing in the direction indicated by the arrow in Fig. 13 the" detent 64 will move the block 66 outwardly against the tension of its spring 67 to permit such detent to pass Without being unseated from the socket 65. Durmg'such motion the shaft 57' and sprocket 56 are locked together so that the one-half rotary movement imparted to the shaft 57 by the rollers 63 is also imparted to the sprocket 56 and through the medium of the chain 48 to the sprocket 47 and frame 46. The sprocket 47 is provided with twice as many teeth as the sprocket 56 so that onehalf revolution of the sprocket 56 rotates the sprocket 47 and the frame 46 one-quarter of a revolution to bring the next set of brushescarried by said frame into operative relation with the shoe rest and shoe being operated upon. Upon the return move ment of the carriage the detent 64 strikes the square end of the block 66 thereby disengaging it from the hub of the sprocket 56 and permitting the return movement without operating such sprocket. In this manner a rotary step by step movement is imparted to the main frame 46 one-quarter of a revolution at each reciprocation of the carriage 28.

A bevel gear 68 is also longitudinally slidably mounted upon one of the squared shafts 39 with a bevel pinion 69 intergeared therewith and rigidly secured to a shaft 70 which in turn is geared by means of spur pinions 71 and 72 with a shaft 73 carrying a heel brush 74.

All the mechanism just described including the bevel gear 68 and the brush 74 is mounted upon a rear. carriage 75 which also travels upon the track 26 and balls 27. The carriage 75 is provided with a hooked detent 76 proportioned and positioned to engage with a hooked detent 77 carried by the carriage 28 both of such detents being spring pressed in such direction as to lock ranc es together thereby temporarily locg the two carriages to operate as a single carriage, the spring for the lever 76 being shown at 7 6' in Fig. 8 with a similar spring not shown for the lever 77. When the carriage 28 moves to the rear to the position shown at Fig. 9 such detents lock together and the carriage is also moved yieldingly forward by means" of a cable 78 passing over the required pulleys and attached 1 to a weight 79 whereby such rear carriage 75 is held yieldingly in engagement with the heel of the shoe being operated upon.

To permit of such yielding engagement the detent 77 in its forward movement engages a plate 80 which serves to lift said detent 77 and disengage it from the detent 76. In other words, at the beginning of travel of the carriage 75 and to provide positive movement therefor the carriage 28 is temporarily locked or connected with the carriage 75 and such carriages move forwardly together for a limited distance when the detent 77 is disengaged from. the detent 76 permitting the carriage 75 to then be actnated solely by the weight 79.

During one reciprocation of the carriage 28 it is desirable that the carriage 75 remain stationary. For this purpose a shaft 81 is journaled centrally of the frame and provided with a cam head 82 having spiral or helical grooves formed in the surface thereof positioned to be engaged by a spring-pressed pawl 83 carried by the carriage 75 so that at each reciprocation of said carriage 75, the shaft 81 is rotated through one-quarter of a revolution. The shaft 81 carries a detent83' in positionjto at, times be raised into position to engage the detent 76 and to move such detent against the tension of its sprin to throw such detent out of position to e engaged by the detent 77 so that during such eriod the carriage 75. does not move forwar with the carriage 28 to a sufficient distance to engage the slot upon the foot rest but is in position to be engaged by the carria e 28 upon its return movement to move it ackwardly. to. again rotate the shaft 81 onequarter of a revolution. By this arrangement the heel brush 74 is applied to the heel of the shoe three times successively following the reciprocation of the carriage 28 but the fourth time the carriage 7 5 and the heel brush 74 remain out of'engagement with the shoe. Carried also by the carriage 28 are gears 84 also. longitudinally.

slidable upon the squaredshafts 39 and intergeared with inions 85 which in turn carry shafts 86 in brushes 87. p

'lhev shafts 86 extend, upwardly throu 'h laterally slidable bearing oxes 88' and t e 1 brushes 87' are held to their. work by the springs 89. The shafts86'are pivoted to their turn carrying side 7 trolled insuch swinging movement one direction by the springs .89 and in the opposite direction by means of a toggle con:- sisting of links 91. and the arms 92 rigidly secured to shafts'93.

The shafts 93 are journaled in brackets 93 and are controlled by means of levers 94; having rollers traveling; along the sides of cam tracks 95, rigid with the base 25. The levers 94; are loosely mounted upon the shaft 93 and have halved hubs 96 adapted for clutch engagement with similar halved hubs 97 rigidly secured to the shafts 93. At one end an abutment 98 is erected in position to engage the rollers 99 on. the levers 94 when they have passed off from engagement with the track tomove the hub 96 out of engagement with the hub 97 By this arrangement the shafts 86 are per mitted to act under the tension of the springs 89 to hold the brushes 87 in operative engagement with the shoe during the movement of the brushes from the toe to the heel of the shoe. When the carriage has reached the limit of its movement 1n this direction the said rollers engage another abutment 99 which moves the hubs 96 in the opposite direction or into engagement with the hubs 97 so that upon the re turn movement of the carriage the rollers 94 are" spread apart by the action of the cam. track, and through the action of the toggles 91 and 92 the brushes 87 are also spread apart out of engagement with the shoe, during the movement of the brushes from the heel toward the toe of the shoe. Springs 98 are provided simply to hold the rollers 94 in .contact with the track 95 when the hubs, 96 and 97 are uncoupled.

To properly position the shoe upon the foot rest 'andto prevent displacement thereof and also to prevent the application of dressing where it is not required or desired a shield 100 .ismounted upon a vertically reciprocatable shaft 101 which said shaft is connectedwith a lever 102 pivoted at 103 to the casing and carrying a roller 104=at its end 0 posite its connection vwith the shaft 101. ivoted adjacent the lever 102 is a lever-105 havin one end disposed adjacent a slot 106, an by" means of the lever 105 the lever 102 may be manipulated. Connected with the lever 105 at the end opposite the slot 106 is a chain or cable 107 passing about a.pulley 108 and a second pulley 109 is attached to a weight 110 in such manner that the chain 107- is under continual strain. Connected with the chain '107 is a lever 111 pivoted as at112 to the rec '401 qulred instantaneous action to the switch a rying a U-shaped positioning member 116 adapted to engage the rear side of a shoe or ankle of a foot to hold such shoe or foot firmly upon the shoe rest 117.

It will, be apparent that the manipulation of the lever 105 from without the housing will serve to withdraw the U-shaped positioning member for theinsertion of the foot .and that the depression of such leverwill also engage the roller 104 and raise the front shield 100. The releasing of the lever .105 will permit the front shield to descend and engage the front of the foot while the weight 110 will serve to move the U-shaped positioning memberforward to also engage the rear of the foot so that by the employment of such two members the foot or shoe 1s accurately'positioned upon the shoe suptact member 122 crank leveri125 is also controlled by the rod port and the front positioning member serves also as a shield-totprevent the applielation of dressing to the ront or top of the s 0e.

The mechanism above described is operated from any approved source of energy as the motor 3.8 and such motor is controlled by the employment of a push button switch indicated at Figs. 17 and 18. The switch referred to comprises a bracket 117 rigidly secured to the interior ofv the casing with a slidable rod 118 extending outwardly through the casing and provlded with a push button 119 upon the exterior thereofadjacent to the handle member 120 by which the lever 105 is manipulated.

Pivoted uponthe bracket blade 121 of'the. switch carrying one conin position for engagement with the other contact member 123 carried rigidly by the bracket 117.

Connected 117 is one nected with any approved form of registering or recording means 134 showing the number of operations of the mechanism.

The timing mechanism comprises a shaft 135 provided with a plurality of cams and a plurality of levers 136, 137, 138 and 139 are pivoted upon a common pivot 140 and in engagement with the cams upon the shaft 135. The shaft 135 is moved with a step by step movement by means of a lever 141 in position to be engaged by abutments 142 and 143 carried by the carriage 28 so that as the carriage 28 reciprocates the abutments 142 and 143 alternately engage the lever 141 upon opposite sides and oscillate suchlever alternately in opposite directions. The lever 141 carries a detent 144 engaging ia ratchet wheel 1445 upon the shaft 135 whereby when the lever is oscillated the shaft .135 and the cams carried thereby are rotated with a step by step movement and the levers 136 to 139 inclusive receive actuating impulses therefrom.

The mechanism associated with the lever 141 is similar to that disclosed in co-pendmg application. Serial No.604409 filed on January 24, 1911, and renewed on December 22, 1915, Serial No. 68296, and comprises springs 146 adaptedto move such lever across the dead center represented by its pivot and a rod 147 connecting said lever with a piston 148 located in a cylinder 149 serving as a dtISh POt to cushion the movements of the lever i141 and prevent the same from jarring and pounding its'limiting screws 150 and 151 when moved across ts pivot under the impulse of the springs 146.

The rod 132 bearing the sign is connected with one of the levers as 138 while the rod 127 which actuates the switch is connected with another of said levers as 136. One of the levers as 139 is connected with the rod 152 which controls mechanism for applying dressing to the top of the shoe by rocking the rod 153. such delivering mechanism being shown-at 154 and described more fully in said co-pending application filed on even date herewith. The other of said levers as 137 is connected with the rod '155 which rocks a shaft 156 which in turn moves a link 157 and actuates' the coin-retaining means 158 of the coin-controlled device which is not herein claimed but which forms the subject-matter of another application. I

By the em loyment of the timing mechanism just above described it will be apparent that theseveral functions of the apparatus are controlled from the single shaft forming a part of such timin mechanism the switch,
